i'm 12 weeks pregnant and found out last friday i have diabetes. they think i had it from before i got pregnant so are saying i'm a type 2. the last three days i've changed my diet as they said. i'm eating what i'm supposed to, and in portion sizes i'm supposed to. problem is my number are still showing up high, and since changing my diet i'm snapping at everything, feeling lightheaded and my heart is rushing every now and then. didn't feel like this till i changed my diet like they told me. surly this isn't normal? i was absolutly fine before i changed my diet.
